P. Bisetti Leaf Yellowing/Tips Browning

[davidc304]

Hey guys, got my boo in order and planted up. Some leafs were yellow upon arrival, but I'm sure that to be expected during springtime and shipment.

But, some of the tips are browning and yellow at the same time. Some of the tips are completely gone. Doesn't seem to be spreading too fast on the plant. I will post some pictures tomorrow, that should better clarification. Any ideas? Time to fertilize? There was some dry fert on the top soil of the plant already.

Doesn't seem to be a real problem, yet. Some of the new shoots that were with it (#1 plants) are definitely taking off big time, 3X the size they were when i got them in like 4-5 days.

One issue we have had, the day i planted them, it rained constantly for 3 days straight. Maybe not an issue. Soil is still moist under the mulch. Ill water them possibly tuesday as it is supposed to rain sunday-monday. They were definitely drenching rains.

I'm not really concerned, i have exp. growing many things, this doesn't seem to be a big problem, but though id ask the experts Thanks guys, like i said, ill post a couple pics tomorrow. Seeya

I have 2 that I planted in November and have a similar problem with one but not the other. Both are located near each other, in same soil type, etc. Both are shooting like crazy. About 2 months ago, one of them decided all the leaf tips would turn brown. Doesn't seem to be slowing it down, as its still putting up lots of new shoots. Even the new shoots leaf out with brown tips though.

I dug up a wheelbarrow full of roots from climbing vines (look like taters!) from the area where the browning plant is about 2 weeks ago. I'm waiting to see if that helps it out any.

Well went out to take some snapshots, got a few. Theres a decent portion of all of the plants doing this. Again, they were recently planted this tuesday, 5-15-07. Even my P.Decora is doing it. Could it be too much water?? Not enough fert? The problem seems to be much worse than i thought last night. My decora (HPIM5623) is covered. The others not as bad, but getting worse.

Thanks for looking guys.

David, I don't see anything unusual in your pictures, a number of things can cause the tips to brown, shipping is quite stressful for bamboo even when done well. I would not worry unless you stand back and see the entire plant looking like it is failing. Just keep an eye on the overall appearance, note if it keeps making new leaves as expected and don't over water as a reaction. Stick your finger a couple of inches into the soil and if its wet don't water, if its dry go ahead.

Like i said above, we had WAY TOO MUCH rain the days after i planted. But the soil is moist under the mulch. Yeah i didnt think i should really go off the hook over this. The boo is VERY wind resistant so far, as we have had slightly higher than normal winds. The brances are still very flexible, which tells me water is ok. The wind will practically bend them (just 1-3 of them) over on the ground, they spring right back up. Heres a shot of the whole planting.

So, should they be making leaves all summer? I see some shoots from the other branches, should i expect all the others to follow?

Thanks!

[davidc304]

Well, now all tips on ALL leaves on all plants are brown. Still new growth shoots coming out of all plants.

Is this what they do when they lose leaves in the spring, or just shock to being replanted? Spring is pretty much over here, hitting mid 80's for the past week

These plants were not fresh divisions, they grew in pots for several months.....

All i have done is water them periodically, not too much though. Soil is still moist under mulch. I am going to fert this weekend and just let them go the rest of the summer.

Appreciate any responses. Thanks guys!

Could be too wet if your soil is heavy or poorly drained. I wouldn't water until your top 1" soil dries out. Also I'd hold off fertilizing until the plants look better. In your location I think you could plant them, stand back and watch them grow.

[davidc304]

Thanks Thuja, i think your right. I haven't watered but 2 times in the past 2 weeks. Enough rain to take care of it. And yes, soil is very heavy clay. Ill fert this fall instead, thanks a bunch. Seeya!

[davidc304]

Well, still not much change in my leaves, for those who care
But they are looking good and all are making lots of new leaves. Should i cut some bad leaves off?

But, one of my plants has definitely taken root, it sent a shoot up about 3-4inches past my mulch area. Holes are 16" wide. Seems kinda far for bisetti, but i wont complain It definitely tells me bamboo can trudge through some heavy clay, quick and easily. I thought my soil was very poor, mostly clay and rocks.

I have 5 bisettis, 2 of them shot up new shoots very soon after planting, but the smaller 3 haven't really done anything. I don't guess i should expect anything until next spring from those. They were the smaller #1 plants, but still very nice. But the other 2, i definitely got a good deal on. I would consider them #2 in size/height/new shoots.

My 1 decora is just sitting there. Cant wait to see her go as well.
But i must say, so far so good.

Ill take a couple snaps of the new stuff. Any suggestions / comments? THANKS GUYS AND GALS!

You could cut the bad leaves off if they detract from the appearance, but the more leaves (food production) the better initially, even if they are partial leaves.

I'll bet most of your growth is now occurring underground. Sounds like you plants are establishing themselves nicely, and in spring you'll be amazed what you see, and the following spring you'll be astounded.

Looking forward to see some pix along the way.

Well after our little mini-monsoon rain of about a week, i have SEVERAL new shoots from the others who didn't produce yet this spring.

One of them has 2, one has what seems to be like a cluster of 4...They are all VERY small shoots compared to the ones already fully grown...

And, with all of this new growth, i think to myself, i am not watering enough? These rains were long, heavy and drenching. The ground has been sopping wet for a week.

So now, only my biggest bisetti and the lonely decora have not produced this spring/summer. Cant wait until spring again lol.

[davidc304]

Well, one of my plants is yellowing much more than the others now. They are all slightly yellow somewhat. Full sun too.
Now, at this point in time, i have no new growth...is this normal? It is starting to look unhealthy. But, it did send up new shoots about 1mo after planting....

During the summer, there were new leaves forming(shoots?) off of the branches...now, none. All 6 plants, none..

I have read, and feel, with my heavy clay soil, is probably alkaline. Can i fert or try to change PH this late in the season with like, 1/4th strength? I only ferted probably some time in late june, early july. The nights are getting down to 60deg F.

Or, should i just leave them alone and do it come spring?

I gave them a dose of superthrive about 2 weeks ago, should i dose them again? It didnt seem to help any, or hurt.

Thanks guys......

Not sure about the yellowing but ~10-20% yellow leaves could be normal if the plants are shedding old leaves. My opinion is that it's best to let the plants slow down now in preparation for winter. You don't want to stimulate lots of new shoots late summer into fall. The youngest shoots can get zapped by frosts.

David,
I have clay soil with a pH of 7.5. On some of my bamboos the leaves will turn a light green or light and dark green stripes. To turn the leaves a darker green I spray the plants with Lilly Miller Chelated Iron Plus and they normally start to green up in about a week.

I also use ammonium sulphate in the spring and on my Shibataea kumasaca I added sulphur to the soil before planting and scratched into the surface every other year after that.

The ones that seem to turn light green for me are.
Shibataea kumasaca
Indocalamus tessellatus
Phyllostachys mannii 'Decora'
P. stimulosa

I normally spray the Iron Plus in the Late Summer/Fall when the plants start to turn a light green. I sprayed a couple of plants last weekend and I still need to spray my Decora.
